Abstract
Various efforts have been made to minimize the corrosion damage of deicer. However, due to the nature of the deicer that needs to lower the freezing point, the concrete damage due to the repeated freeze-thaw cycle caused by the penetration of the deicer solution into the pores of the concrete could not be fundamentally suppressed. Therefore, a basic study was conducted to minimize the deterioration of concrete by suppressing the water permeability of the concrete surface with penetrating sealer incorporated deicer. Dynamic light scattering and zeta-potential analyses were performed to evaluate the mean diameter and degree of dispersion of the suspension in the aqueous solution of the prepared liquid deicer. Experiments confirmed the water permeability to be 44%–58% that of the untreated control group, and the mass of certain concrete specimens after freeze–thaw cycling tests tended to increase. In addition to the reduction in water permeability, in this study, an increase in the mass of the specimen in repeated freeze thaw cycle was confirmed, which is Liquid deicers with penetrating sealers have the potential to improve the durability and reduce the deterioration of concrete.
